Sigh.  In /this case/ they are the same, because the data directly
follows (the char* member doesn't even really have to be there, it's
just convenient. It could literally be just 'char', for example).  The
data always did directly follow, and this has all been working just fine
for ages now.  You just didn't bother to understand the existing LV2
MIDI before trying to extend it, and an awful lot of pointless ranting
about cache and optimisation or whatever was the result.   

Touche, smartass :P
